All parts of an aeroplane are subject to corrosion all the time. You can slow down the rates of corrosion by keeping air and moisture and contaminants away from the surface of the metals by applying paints or sealants. One of the worst places for corrosion is around the toilets and galleys. The water in these area's contain a lot of contaminants and if the paint coatings are not perfect, the corrosion begins, and aluminum will disintegrate very quickly. There are many types of corrosion. Corrosion can start from the inside of the metal, called inter granular corrosion. External paint wont stop this. All corrosion is bad and if not removed and reprotected will cause structures to fail.
Aircraft manufacturers prevent corrosion by using corrosion-resistant materials, applying protective coatings, and regular maintenance such as washing and inspecting the aircraft for signs of corrosion. Additionally, manufacturers may also design aircraft components to minimize areas where moisture can accumulate.
The anode is more prone to corrosion in a galvanic cell.

The prevention and control of corrosion on aircraft is primarily the responsibility of the aircraft manufacturer, airlines, and maintenance organizations. Manufacturers design aircraft with corrosion-resistant materials and coatings, while airlines and maintenance crews are tasked with regular inspections, maintenance, and repairs to prevent and address corrosion issues. Regulatory agencies, such as the FAA in the United States, also play a role by setting safety standards and guidelines for corrosion control. Overall, it is a collaborative effort involving multiple stakeholders in the aviation industry.
Taking a look at the industrial areas,the corrosion rate seems to be higher since the industrial area can be said to be a combination of both an urban centre and a rural centre and invariably has a corrosion rate= corrosion rate of urban + corrosion rate of rural areas
Delhi is prone to Earthquake. Prone areas - The areas which are near to Yamuna bank are very much prone to the earthquake. East delhi is the most earthquake prone area. Some areas are- Shahdara, Mayur Vihar - I, II, III, Laxmi Nagar and nearby areas, Gurgaon, rewari, noida

Corrosion which is an oxidation reaction needs oxygen and water. Water in the form of condensation is readily available in cold areas. Hence corrosion go faster in cold areas.
Intergranular corrosion in metallic frames of aircraft can lead to localized weakening and structural failure. This type of corrosion attacks the grain boundaries, which are important for maintaining the structural integrity of the material. Failure to detect and mitigate intergranular corrosion can compromise the safety of the aircraft and lead to catastrophic consequences.
Disaster prone areas are in the coastlines of tropic regions.
